Multi-lumen tubing is critical to a wide range of medical device applications from interventional catheters to drug delivery systems where separate fluid or wire channels must coexist within a single catheter shaft. Fobos Polymer specializes in manufacturing high-precision PTFE multi-lumen tubing for medical device OEMs and healthcare suppliers worldwide.
In interventional radiology and cardiology, multi-lumen catheter shafts enable simultaneous infusion of contrast media, guidewire navigation, and drug delivery through independent lumen channels within a single tubular structure. In peripheral and neurovascular drug delivery systems, separate lumen channels allow targeted therapy administration without cross-contamination. In diagnostic catheter assemblies, multiple channels accommodate sensors, electrodes, and fluid lines simultaneously, enabling comprehensive clinical assessment within one minimally invasive device.
PTFE, known commercially as Teflon, is the material of choice for these demanding medical tubing applications due to its exceptional chemical inertness, near-zero friction coefficient, biocompatibility, and thermal stability from cryogenic temperatures to +260C. Virgin PTFE and ISO 13485-compliant modified PTFE compounds are used exclusively in Fobos Polymer’s medical tubing production to ensure material safety and performance consistency in clinical environments.
Product Overview
Our PTFE Teflon Medical Multi-lumen Tubing is manufactured from Virgin PTFE and modified PTFE compounds, offering exceptional chemical inertness, low friction coefficients, and thermal stability from cryogenic to +260C. Available in standard AWG sizes and custom lumen configurations, these tubes are designed to meet the stringent requirements of ISO 13485-certified ISO 13485-certified medical device manufacturing. Fobos Polymer supplies medical device OEMs globally with a complete range of fluoropolymer tubing solutions.

Manufacturing Process and Quality Assurance
Every batch of Fobos Polymer multi-lumen tubing undergoes rigorous dimensional inspection including lumen diameter verification, wall thickness measurement, and surface quality assessment. Incoming raw materials are traceable and certified, and production parameters are recorded in compliance with ISO 13485 document control requirements. Finished tubes are packaged in cleanroom-compatible packaging to maintain sterility and dimensional stability during storage and transport.
Customization and OEM Supply
We work closely with medical device OEM customers from initial product specification through to mass production. Our engineering team can produce prototypes from customer drawings or CAD files, conduct technical qualification runs, and scale to production volumes. Tooling and mould costs are quoted separately, and production volumes can start at modest quantities, making Fobos Polymer accessible to both emerging startups and established global OEMs.
